Railcar Couplers for Wheel Loaders or Tractors

Dymax Railcar Couplers are attachments that adapt to wheel loaders or tractors enabling operations such as coops, aggregate and load transfer facilities, port and terminal railways and rail yard applications to safely pull railcars. Dymax Railcar coupler systems are available to fit the front and rear of Wheel Loaders and Tractors with a minimum of 115-130 horsepower for pulling small car volumes.
They feature integrated free slide frames. Available with nylatron slide bearings or in hydraulic side shift. Each model features a standard AAR cast railcar knuckle. When equipped with the vertical float option the coupler will adjust, if the loader is traveling on uneven terrain.
We offer specialized design services and work with our local tractor dealers to provide turnkey ready railcar movers using tractor base platforms. These machines are highly versatile and are ideal for pulling low carload volumes. Contact us today to learn more about DymaxRail’s innovative solutions for moving railcars.
